On Monday afternoon, Feb. 13, I visited a farm outside Millsboro that was experiencing heating and ventilation problems. This farm had purchased two new high performance timer fans and was only able to pull .05 static pressure.

After much investigation a smoke test revealed that air was leaking around the foundation where the sill plate meets the block foundation. I recommended to the grower that he seal this area with a commercial sealer. Static pressure tests are performed on a closed poultry house with 2- 36 inch fans or one 48 inch fan running to pull a vacuum. All areas should be completely closed to pull maximum static pressure.

Smoke from an insect fogger (using baby oil), a commercial smoke stick or even a bee smoker can then be used to direct smoke outside the house along the foundation, sidewall or any suspect areas where the affected area will pull the smoke into the building. This leak can now be easily seen. ~ Bill Brown
